确保您的计算机上已经安装了DirectShow。如果没有，请从Microsoft官方网站下载并安装。

打开Visual Studio，然后创建一个新的C++项目。在“生成”选项卡中，选择“多线程应用程序（/MTd）。

在项目中添加一个名为IFilterGraphBuilder的类，该类将负责构建整个过滤器图。在.cpp文件中，添加以下代码：

#include <windows.h>#include <directshow8.h>#include <afxext.h>using namespace AfxExt;class IFilterGraphBuilder : public CFilterGraphBuilder {public:    IFilterGraphBuilder() {        m_pFilterGraph = new CFilterGraph();    }    virtual ~IFilterGraphBuilder() {        delete m_pFilterGraph;    }    virtual HRESULT BuildFilterGraph(void* pContext) {        HRESULT hr = S_OK;        m_pFilterGraph->AddFilter(m_pSource, m_pDestination);        return hr;    }private:    CFilterGraph* m_pFilterGraph;};
